Guerrieri entered the pro ranks as a first-rounder of the Rays in 2011, and he remained a high-end prospect for a little while after that. However, Guerrieri – also a former Blue Jay – could now be on his way to his fourth organization at the age of 26. While Guerrieri did pitch to a 3.47 ERA/3.33 FIP with 9.66 K/9 and 3.72 BB/9 in 36 1/3 innings as a member of the Rangers’ Triple-A affiliate in 2019, he logged a bloated 5.81 ERA/5.38 FIP and 9.23 K/9 against 7.52 BB/9 across 26 1/3 frames at the MLB level.
Pelham, 24, first joined the Rangers as a 33rd-round pick in 2015. He made a brief debut in the majors in 2018, though he threw all 32 1/3 of his innings between Double-A and Triple-A ball this year. The hard-throwing Pelham recorded an unsightly 11.97 ERA with more walks (40) than strikeouts (37) during that span.
